To all whom it may concern:

Be it known that 1, JOHN H. GILMAN, a citizen of the United States, and a resident of Ottawa, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in VVagon-Dumps, of which the following is a full, clear, and exact specification.

My invention is concerned with wagon dumps of the type in which the front wheels of the wagon LIQSHSPGIICleCl from an overhead support, and 1s deslgned (1 to insure the accurate placing and retaimng of the rear end of the wagon in its proper relation to the cross conveyor While its contents are being discharged, and (2) to increase the stability of thestructure where it is portable.

To this end my inventioncon'sists in certain novel combinations of elements which will be fully described in the body of the specifications and particularly pointed out in the claims.

To illustrate my invention I annex hereto two sheets of drawings in which the same reference characters are used to designate identical parts in all the figures, of which,

Figure 1 is an end elevation of an indoor dump employing my invention; Fig. 2 1s a side elevatlon of the same. Fig. 3 is a' plan view of the frame and tie rods pivotally connected thereto.

va'tion of the swinging frame, showing the wheels resting thereon.

In carrying out my invention for indoor dumps I provide in it suitablem'e'ans for which are preferably triangular in shape and may be'made of one or two pieces of material as desired and which, as seen in Fig. 5, extends up above the plane of the tops of the front wheels of the wagon so as to insure stability and prevent the possi- Fig. 4; is a perspective. view of my invention employed in the port-. able wagon dump; and Fig. 5 is a side ole-- Specification of Letters f at e nt.

bility of the frame tipping, as would inevitably occur with the connections hereinafter described if they were omitted or did not extend upward as described. r

The lower ends of'the bails (15) are se cured to the rectangular frame (16), which preferably consists of the two longitudinal members (17) and the two transverse members (18), the frame of course being of a suitable length and width to receive and support the two frontwheels of an ordinary farm wagon. This frame, of course, maybe composed of wood or of metal;

To prevent the shifting of the hind wheels of the wagon while the frame (16) is being raised with the front wheels of the wagon thereon, I pivotally connect preferably to each endof the frame (16) a tie rod (19), the other end of which is pivotally eonnected, preferably to the floor, where it is an inside elevator, by any suitable means,

such as the eye pieces (20), which are located at a point near where the hind wheels of the wagon rest when the front wheels are upon the frame (16). When the shaft (11) 1s rotated te wind up the chains, it will be obvious that the tie rods (19) prevent the possibility of the frame (16) rising in a straight line and causing the rear' wheels of the wagon to be misplaced, as the frame (16) and accordingly the front wheels of the wagon must move through the arc of a circle preventing the rear end of the wagon from having any longitudinal movement. Where the frame (16) is used in an indoor construction, the floor may be recessed as indicated in the dotted lines in Fig. 2,'so

that the frame in its lowermost position may rest in the recess, if desired, to prevent the ar, resulting from the front wheels of the wagon being raised over frame (16) where it rests on th top of thefioor. In Fig. 4, I have shown my invention as applied to a portable wagon dump, adapted for use in connection with a portable elevator (21) and a cross conveyor (22). As is customary in this class of devices, the elevator, cross conveyor and dump are all driven. from a single power shaft (23), which has suitable driving connections with the elevating chains and bars (24) and likewise suitable driving connections (25) with the cross conveyer (22,) which is adapted to be moved in and out of position, so that when the rear wheels of the wagon rest on (28), and the base extensions (29) are preferably detachably secured to the bottoms of the side frames, so that it can be transported more readily, and have their outer ends connected by the bottom cross piece at 26). V The braces (30), preferably detachably secured to the outer ends of the extensions 29) and toward the tops of the side frames (27), serve to add to the rigidity of the structure, the complete frame work thus being one that cannot be readily toppled over, especially when the'stakes (31) are driven in the ground to hold it in place. The extension (32) of the driving shaft is connected with suitable gearing (33) by which the .flexible members, such as the chains, are wound and unwound by any de-' sired mechanism, such, for example, as shown in Figs.- 1 and 2. The specific form of this gear 33 and its connections with the chains 10 form no part of my present invention, and any desired form may be employed, such, for instance, as those shown in my application No. 673,466, filed January 25,1912. In this form the chains (10) are likewise connected to the bails (15), which are in turn connected to theframe (16), which has the tie rods (19) connecting it to the bottom cross piece (26) as before.

The operation of the portable form of my invention will, of course, be the same as that of the stationary form.

)Vhile I have shown and described my invention as embodied in the form which I consider best adapted to carry out its purposes, it will be understood. that it is capable of modifications and that I do not desire to be limited in the interpretation of the following claims, except as may be necess sitated by the state of the prior art.

What I claim as'new and desire to secure by Letters Patent of the United States is:

1. In a wagon dump, the combination with a framework, of a pair of flexible members suspended therefrom at a considerable height, means for winding up said members, rigid bails suspended from said members at or above the level of the top of the front wheels of a wagon when they are unwound, a rigid wheel-supporting frame connecting the bottoms of the bails and upon which the front wheels of a wagon are adapted to rest, and a pair of tie rods of a length substan-.

tially equal to the length of the wheel-supporting frame pivoted at one'end to the frame and at the other ends to the framework toward where the rear wheels of the wagon rest, said flexible members and tie rods constituting the only connections between the framework and the wheel-supporting frame and its bails, substantially as and for the purpose described.

2. In a wagon dump, the combination with a framework having bottom side pieces substantially ofthe length ofa wagon, a

length substantially equal to the length of" the wheel-supporting frame pivoted at one end to the bottom cross piece and at the other ends to the adjacent corners of the wheel-supporting frame. 7

3. In a portable wagon dump, the combi-' nation with a frame having bottom side pieces adapted to be folded at the middle and when extended substantially of the length of a wagon, a bottom cross piece at the rear end, side frames at the front end, a top cross piece at the'top of the side frames, and detachable brace rods extending from the rear ends of the side pieces toward the tops of the side frames and connected thereto, of a pair offiexible members suspended from the top cross piece, means for winding up said members, rigid bails suspended from said members at or above the level of the top of the front wheels of a wagon when they are 7 unwound, a rigid wheel-supporting frame connecting the bottom" of the bails and upon which the'front wheels are adapted to rest,'and a pair of tie rods of a length substantially equalto the bottom cross piece at the rear end, side length of the wheel-supporting frame pivoted at one end to the bottom cross piece and at the other end to the adjacent corners of the wheel-supporting frame.

In witness whereof, I have hereunto set my hand and a'HiXed my seal, this 3rd day of March, A. D. 1910.
